Aside from healthy eating, he hits the road on his bike! He loooooves biking! That's how he made the cover of Bicycling.

Biking even kept him centered when he became a huge star after Grey's Anatomy. He said:

"Psychologically, getting back on the bike really helped me. It was hard to weather the success of Grey’s, but I found I could go for a ride and get centered. Cycling also taught me a lot about managing discomfort. When you leave your comfort zone, you learn how to manage your emotions and to stay focused."

So great he found such a healthy coping method instead of drinking or doing drugs.

He takes his biking really seriously, even going as far as to shave his legs!
